(this one will support the infinite 'Program Change' Value-to-Delta algorithm, because this little keyboard does something quite useful: as soon as 'Program Change' reaches 128 it restarts at 1 again. It also does the reverse of course, when reaching 1, if 'PROG -' is pressed again, it jumps to 128. This allows me to make it truly endless to the "eyes" of Reason, no matter at what value the keyboard is, it will always return a +1 or -1 delta to Reason. This is why I made Patch selection the default control for this one)

Start Reason, go to 'Edit', 'Preferences', select the 'Keyboards and Control Surfaces' page, press 'Add', select 'M-Audio' in the Manufacturer pull-down list, then choose Model 'MidAir 25 (Special)' if you want to use 'Program Change' to select the current Track. Provide the correct MIDI input (or press the 'Find' button and play some keys on your MidAir) , press the 'OK' button and you're done :)

I plan to release a Generic MIDI Keyboard with the 2 types of Value-to-Delta conversion algorithm (the one included with Trust keyb and the other used with MidAir), so people with small'n'simpler MIDI keyboards that have at least 'Program Change' can use it with Reason for something useful :)
